摘要：

The reverse Perlin effects observed for all C-H 1J coupling constants in 1,3-dithiane, i.e., 1J(C-H(ax)) > 1J(C-H(eq), seem to support the existence of a dominant sigma(C-S) --> sigma* C-H stereoelectronic interaction, which leads to a weakening of the equatorial C-H bonds in this heterocycle.
